. M-Acmnnr'on EMBOSSING CURTAIN-POLE RINGS I Application filed June 17,

This invention relatesto improvements in machines for'i'mpa'rtingornamentation to the surfaces of cnrtainpole rings and particu larly tothe conventional ring out from wood.

.In the instant case, the machine is designed and constructed to effectthe surface ornamentation Of; Wood rings by means of a branding roll butwe desire it to bennderstood that for surface ornamentation of ringscomposed of metal or of material which permitsof easy impressionwithout. the use of heat, the heating means shown'may be'omitted.-

' The main objectof the present invention is to provide a verysimple andefficient ma chine for the purpose spe'cifiedwherein the active elementsaremoved to exert pressure on the ring to be ornamented by means ofcompressed airwhich pe'rmits'of great variations in the degree ofpressure exerted on the ring and alsopermits of'easy control of theoperation 'of'the machine; I 1 A further object of'theinvention'is topro vide a rotatable carrier for the rings which is moved by airpressureto compress, the latter against the ornamenting rolljand by aspring tonormal position and wherein the said spring and air-pressure. means alsocontrol and actuate a, guidefor preventing canting of the ringswhileundergoing ornamentad Other 1 objects" ofthej invention 1' will 'bepointed out or. understood from the following specification. .i r V Inthe accompanying drawings illustrating a, suitable embodiment of themachine:'

ing-rollsand a ring interposed between said ro ls. f p I The frame .ofthe machine includes the table plate 1 on which two bearing supportingstandards 2 and 3 are mounted. The bear.- ngs 4 and 5 carried by saidstandards 2 and 3 receive the end .portions of a shaft 6 which" is.annularly] enlarged between said bearings & and 5' to provide thrustshoulders for engaging the opposed'ends of said bearings The shaft 6 isequipped with a sprocket wheel, 7 at one end over which the sprocketchain 8 is trained forfassociating the same with a companionsprocketwheel 9 on a shaft 10 which is suitably geared to a source of power suchas the electriomotor 11 shown. In the instance illustrated," the shaft10 is journalled in hearings in a gear-box lQ and carries a worm-wheel13 meshing with a worm on the motor shaft 14.

At its other end portion the shaft 6 is equipped with a spur-gear 15having long teeth, for reasons hereinafterset forth, and outwardly ofsaid pinion,'said shaft 6 is equipped with an annularly grooved roll 16.The surface of saidgroove in the roll 16 is provided, in the instanceillustrated, with projecting ornamenting formations which, for example,are adapted to produce impressions in the surface of a ring simulatingthose of hammered metal. Obviously the, surface of said groove of saidroll 16 maybe formed toproduce either depressed or raised ornamentationson the ring surface as. desired.

Mounted on opposite sides ofthe roll16 and suitably supported and heldagainst rotation, are gas-burners 17 having annular rows of gasdischarge perforations opposing the side faces of the roll 16 forcausing gas jetsto impinge upon and maintain said roll: hot. Theseburners 17 are connected by means of'a supply pipe 18 with sources ofair and gas under pressure and delivering mixed airand gas to saidburners 17. This supply pipe 18 is equipped with a valve 19 while theair supply pipe 20 and the gas supply pipe 21 are equipped with valves22 and 23 re spectively.

The burners 17 are supported by a bracket jecting through an opening 30in said plate;

V The cylinder 29 is equipped in its lower face or end with a head 31having a central bore with which'a tube 32 connects, said tubeconstituting an air supply and discharge chamber and being sealed atitslower end by means of the head or cap 33. Between its v ends the saidtube or air chamber 32 is connected with an air supply and dischargetube 34. The cylinder 29 is likewise connected at its'upper end with anair supply and dis charge tube 35. 'B'oth these tubes are connected attheir other ends with the valve casing 36 which is suitably connectedwith a source of supply of compressed air and is equipped with exhaustports. A' valve in said casing equipped with the operating lever 37 isarranged so that, when disposed in one position, it seals the airexhaust port for and connects the air supply tube 34 -with the source ofair under pressure, and when in, an-

other position, shuts off the last-mentioned communication, opens thedischarge port for and connects the tube 35 wit-hthe source of airunder-pressure. v v

7 The piston 28 of thecylinde-r is moved to and held at the lower limitof its movement the lowerlim'it of its movement.

by means of the air under pressure supplied, thro-ughthe tube 35,] andis'forced upwardly by air-under pressure supplied to the chamber 32'through the tube 34, details of c011 struction of the valve and casing36 being omitted. from illustration as well-known in. the steam andgas-fitting arts. A spring 38 is attached at its lower end to the frameelement 39 and at its other'end to a:

pair of arms 40 which are parallel and pivoted at one end tothe block 41on the table 1 andbetween their ends bear upon an arm 42 rigidly securedto: the vertically reciprocable bearing 26 t0 normallymaintain thelatter at The outer free end portions ofthearms 40ers so disposed thatthe openspac'e between them lies normally below the carryingroll'43mounted upon oneiend portion of the shaft 33 jour-- nalled in the.sleeve-bearing 26.. Said roll 43 is provided with an; annular groove inwhich rings 45. to be subjected to the action of the roll 16are engaged,the carrying roli'being; of less outer diameterthan'theopenings intherings 45. I

The arms 40 are normally positioned to permit :the. placing of ari-ngon. the said carrying roll 43 and, as the said roll is raised under theinfluence of compressed air admitted to the cylinder 29 below the pistonthereof and causing the latter and the bearing 26 to rise, the said arms40 swing upwardly so that the space between their free end portionsreceives the. lower portion of the ring 45 carried by'the roll 43 toprevent said ring from canting out of a vertical plane.

The shaft 44 is equippedwith a long tooth spur-pinion which meshes atall times with the companion gear 15 on the shaft 6, said long teethpermittingzsnfiicient separation of the rolls 16 and43 to mount upon andremove rings from the roll 43. Said rolls rotate continuously in'unison,and, when a ring 45.v isinterpo'sedtherebetween and conipressedair isadmitted to the cylinder as above described, said ring 45 will becompressed against the ornamenting surface. formations of the groove ofthe roll 16 and will be rotated to have the ornamentation imparted toits outer surface'under the influence of heat and pressure, in theinstant case.

In operation, a single operator feeds and removes rings successivelywith one hand and operates the valve lever with the other hand tointroduce compressed air into the cylinder following the mounting ofeach ring on the roll 43 and to exhaust the air from the cylinderpreparatory to removing the ring from said roll.
